Learn the BJJ mount: position, weight, the IBJJF three-second rule and typical mistakes. For beginners, with clear milestones and safety rules.
The mount earns you 4 points under IBJJF rules once you hold it stably for 3 seconds [1]. You sit on your partner's torso facing the head, with two knees or one foot and one knee on the mat. At most one of your partner's arms may be trapped under your leg for the points to count [1].
The honest answer: mount looks like a strength position but is a balance position. Whoever holds it with muscle loses it at the first bridge. Realistically it takes a few weeks until you hold it against light resistance. That is a practical estimate.
Important for understanding: mount is rarely an endpoint. It is a place where you gain options because your partner can no longer breathe or move freely. Accept that and you become calmer, and calm mounts last longer. Your goal in this guide is therefore not the quick attack but a mount that still feels good when your partner is working. That can be built in small, calm practice rounds.
Sit low on the torso, knees close to your partner's ribs, hips heavy. If you perch on tiptoes you are catapulted at the first bridge. Milestone: you can sit for 20 seconds without holding on.
Your partner needs room for his hips and arms. You close the gaps: knees tight, lower legs moving along. The scoring rule demands: mount only counts when you are free of the half guard and have at most one arm under your leg that does not extend beyond the shoulder [1].
When your partner bridges, go with it: hips forward, knees firm, hands not posted on the mat as a crutch. That turns his effort into your weight shift.
After 3 seconds of stabilisation the points are yours [1]. Now you decide: an attack as taught by your coach, an improved position, or a transition to the back. Whoever just sits wastes the advantage.
Before you hold the mount well, you should know how it feels underneath. Let yourself be mounted in positional rounds and try to escape. Whoever knows the view from below understands why weight, tight knees and a calm upper body matter. That is practical knowledge, not a study.
In mount you sit on chest and ribs: never put full weight on the rib cage when your partner needs air. Hands that block the nose or mouth are illegal [1]. Injuries happen mostly in free sparring: in a study of Hawaiian tournaments the rate was 9.2 per 1,000 exposures [2], and in a survey of 1,140 athletes 77.6% of injuries occurred in sparring [3]. Dose weight and speed, especially in your first months. Against clearly lighter partners you need not give your full weight: control also works with half the load. And if your partner panics because he feels cramped, you give space and calm the round instead of pressing on. A tap from your partner means: release immediately. A tap for breathlessness counts too: if your weight slides onto the rib cage and your partner taps, you take it off at once. This does not replace supervised training.
Get heavy before you get fast. Deliberately give your partner a bridge to feel how you go with it. A calm, heavy mount is harder to bridge than a frantic one. Exhale as you lower your weight and feel how your partner reacts.
4 points under IBJJF rules, if you hold it stably for 3 seconds [1].
In mount you sit on the front of the torso; in back control you hang on your partner's back with your heels between his thighs. Both score 4 points [1].
In competition 3 seconds of stabilisation are enough for the points [1]. In training you stay as long as you practise something useful: holding, taking space, transitioning. Plain sitting without a goal teaches you little.
A mount variation in which one leg is brought up so you sit higher and can control arms. As a beginner you first understand the standard mount.
Yes, if you dose weight and release at the first tap. Most injuries occur in free sparring [3].
